Motorola Mobility is a subsidiary of Lenovo Group focused on designing and manufacturing consumer mobile devices. Headquartered in Chicago, Illinois, the company was formed on January 4, 2011, following the split of Motorola Inc., with Motorola Mobility retaining smartphones, cable modems, and set-top boxes, while Motorola Solutions kept enterprise products. Best known for its Android smartphones, Motorola Mobility was acquired by Google in 2012 for $12.5 billion, primarily for its patent portfolio. Google later sold most of the company to Lenovo in 2014. Today, Lenovo markets devices mainly under the Moto brand, with Motorola remaining part of its identity.
